Product Details

Our Stainless Steel Tee price, ASTM A250 ERW Welded Tubes, Bends have always been to create value for customers as the goal, we constantly strive for improvement in technology so as to produce high-quality, low-cost products for customers. Our company has always adhered to the business tenet of 'integrity-based, quality first'. Merchandise have been exported to many countries and regions.

Cold Formed Welded Structural Hollow Sections are formed at ambient temperatures and are produced in accordance with standard EN 10219-1: 2006. There are more and more manufacturers of cold-formed hollow sections, which makes their products more widely used. In Germany, hot-worked structural hollow profile (HFSHS) products are usually 24% to 54% more expensive than cold-formed products.
